HosE-WAsI-IER.

To all whom it may concern:

Be it known that I, WALTER R. CALvERT,a citizen of the UnitedStates,residing at San Antonio, in the county of lBexar and State ofTeXas, have invented a new and. usefulV f vILIose-Vlasher, of which thefollowing is a i speciiication.

v*This yinvention relates to improvements in hose washers and moreparticularly to that class which are provided with means for fpreventing their accidentalldetachment or displacement from a hose. Y

` yAn object of the present invention is to provide a hose washer withnovel means for effectively securing the same to the end of a hose.

A further object is to provide a h ose washer including a resilient wireretaining member of unique formation for holding the washer in place. Y,

- Vith the foregoing and other objects in view which will appear I' asthe description proceeds, the invention resides in the combinationand-arrangement of parts and-in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made withinthescope of what is claimed, without departing from the spirit oftheinvention.

In the drawingsaccompanying this speciication and forming'a partthereof, the'preferred embodiment of my invention is illustrated, inwhich Figure 1 is a view in longitudinal sec- Ationof the fend portionof a hose with the improved hose washer disposed therein and view takenon the line 2-2 of Fig. 1. Fig. 3-is a` perspective view of theresilient wire attachingelement.

` In the drawing, there is illustrated a ro- Y tatable female or socket,member 4 of a hose couplingV which'is carried by the outer end of anipple or hose attaching member 5 having the end of the hose 6 engagedthereon.

The inner end of the nipple 5 forms a shoulder 7, which is utilized forthe engagement 'of the washer holding or retaining'element.

The hose washer, designated 8, Vis preferr ably formed of two. annularsections 9 and 10 which are vulcanizedv or otherwise united. The washer,when in position, is disposed g I ySpecification of Letters Patent.

within vthe coupling member 4 against the outer end of the nipple 5 forthe'contact therewith, of the male coupling member, to.

provide a tight joint.

g `The retaining orholding element'which is formed from a length ofsuitable wire, has an intermediate semi-circular portion 11 embedded inone half of the washer, portions 12 projecting inwardly from the ends ofthe semi-circular portion 11, and complementing resilient arms 13projecting from. the inner ends vof the portions 12. The portions 12project beyond the edge of the aperture or opening of the washer, asseen inv Fig. 2, and the arms 13 are under tension for causing them toseparate. arms 13 are provided with the outturned hooks P at their freeends, and the bills .14 of the hooks have their free ends beveledinwardly, as at 15, to provide sharp points which are engageable withthe vshoulder or inner end 7 of the nipple 5.

The washer 8 is provided with inwardly projecting lugs 16 embracing theinnerends of the portions 12, and the bends between thesaid portions 12and arms 13, whereby the said lugs 16 will protect the said bendsagainst corrosion, and willv also assist in holding the arms 13 inoperative position. In assembling the wire retaining element with thewasher, it is preferable to place the portion 11 of the'wire elementbetween the sections or layers of the washer or gasket prior tovulcanizing or uniting the same, in order that the portions 11 and 12 ofthe wire element will be properly embedded in the washer after thevulcanizing operation.

In applying the washer to the hose, the arms 13 are first pressed towardone another so as to readily enter the 'nipple or The sleeve 5, and thehooks P may then readily Y ment, and the peculiar assemblage of the lwhat I claim is In a device of the character described, a washer, and aretaining device therefor em` bodying a wire having anl intermediatesemcircular portion embedded in one half of the washer, portionsprojecting inwardly from the ends of the said semi-circular portion, andcomplementing resilient arms projecting from the inner ends of the saidinwardly-projecting portions, the arms having outturned hooks at theirVfree ends, and the 15 washer having inwardlyprojecting lugs embracingthe inner ends of the said inwardlyprojecting portions andthe bendsbetween the said inwardly-projecting portions and arms. Y

In testimony that I claim the foregoing as my'own, I have hereto aiixedmy signatureV in the presence of two witnesses.
